SPECIFICATION forming part of Letters Patent N 0. 739,628, dated September 22, 1903.

Application filed December 13, 1902. Eleriel No. 135.078. (N0 model.)

for Bottles, Jars, and'Similar Receptacles, of-

which the following is a specification.

This invention has reference to stoppers,

covers, or closing devices for jars, basins,

bottles, or other receptacles or vessels.

According to the invention the cover, stopper, or the like is provided with a downwardlyprojecting circular rib adapted to enter a corresponding annular groove or recess at the mouth of the receptacle. A compression washer or other suitable packing may be provided to insure an air-tight joint. Suitable fastening devices maybe provided for securing the cover or the like in position and notches or holes to facilitate the application of such fastenings may be provided where necessary. 7 e

In order that the invention may be clearly understood and readily carried into practice, I will proceed to describe the same more fully with reference to the accompanying drawings,

which illustrate various applications thereof.

In the drawings, Figure 1 shows in perspective a basin provided with a cover or lid according to this invention and with a metal clip or fastening device. Fig. 2 is a similar view of a like arrangement in which the cover is secured by means of string. Fig. 3 is a section of a cover such as shown in Figs. 1 and 2. Fig. 4: is a detail view to a larger scale in vertical section on the line a a, Fig. 1, showing the manner in which the tight joint is obtained, the parts being separated for the sake of clearness. Fig. 5 is a similar view showing the parts in the closed position and secured by the clip end of the fastening device. Fig. 6 shows in perspective the application of the invention to a cylindrical jar, but with a somewhat different fastening device tothat shown in Fig. 1. Fig. 7 shows a modification of the invention applied to a bottle=stopper. Fig. 8 in perspective shows a further modification.

a is the cover or lid.

12 is the body of the basin or like receptacle.

0 is the circular rib with which the covera is provided, and d is the annular groove or recess into which the said rib c fits.

The groove cl may conveniently be formed, as shown, in the top edge of the rim or lip c, with which the basin, jar, or other vessel is provided in the usual way.

f is a disk of paper or other suitable material which is placed overthe top of the basin or against the under side of the-cover. The edge of this paper is forced into the groove d and serves as a washer or packing device to give an air-tight joint besides preventing the contents of the vessel coming into direct contact with the cover or lid.

gis a metallic clip or fastening device, the

ends of which are bent over or hooked, as at g, to engage under the rim or lip e.

It represents notches formed at opposite points on the edge of the cover or lid to serve as seatings for the ends of the clip g, the said notches being inclined or beveled, as at '6, to avoid sharp bends such as might weaken the metal of the clips.

In the arrangement shown in Fig. 1 the clip 9 consists simplyof a metal strip-say of thin steel-bent down at its ends into the form shown in Fig. 5, and this strip is inextensible, its ends having to be forced or sprung into position. At its middle it is provided with a ring or loop j, connected to it by passing through a fold or eye k, formed in the clip. This ring or loop serves as a finger-piece for lifting the jar and can be folded down, so as to lie flat on the cover when not in use.

In the arrangement shown in Fig. 6, however, the clip is made so that it can be elongated to allow of its ends being drawn apart, so that they can be more readily slipped over the edge of the cover. For this purpose instead of having a separate ring at its middle it is formed into a bent finger-piece or loop I. This loop serves for the lifting up of the jar or receptacle and also as a spring which is capable of yielding and opening at its lower end to permit of the clip g'being stretched when passing the ends thereof over the lid. If it be desired to use string to fasten the cover or lid in position instead of a metal clip, this may be done as shown in Fig. 2. Y

7 provided by the rib c.

In this case the cover or lid is provided with small notches m for the string to engage in, and corresponding notches n are formed at the bottom or under edge of the basin.

In the particular example shown in Fig. 2 the strings are arranged to cross each other at right angles, but this is not essential. In

fact, the cover may be adapted to be fastened either by a clip or by string, as may be desired, and for this purpose it may be provided both with a pair of clip-notches h and also with a pair of smaller notches m at .right angles to these latter, the bottom or under edge of the basin would also be provided with four notches n, coinciding with the notches h and m. This form of construction is shown in Fig. 8 of the drawings.

The disk or washer f above referred to, instead of being formed of paper may be composed of waxed textile fabric or other flexible material that will not readily tear, or instead of using such a disk or washer a liquid or plastic sealing substance may in some cases be introduced into the annular groove d to form an air-tight joint, the said substance being of such a nature that it will remain solid at ordinary atmospheric temperatures.

In some cases the cover or stopper may have a central projection on its under side to fit into the mouth of the receptacle. Such an arrangement is indicated in Fig. 7 as applied to a bottle-stopper, 0 being the central projecting portion or plug which is adapted to fit into the mouth of the bottle. The said plug 0 thus forms an auxiliary seal to that It will also be readily understood that instead of the rib being formed on the cover and the groove being in the vessel the arrangement maybe reversed, the groove being formed in the cover and the rib on the vessel. The former arrangement,

which is that illustrated in the drawings, is the one which it is preferred to employ.

WVhat I claim, and desire to secure by Letters Patent of the United States, is-

1. The combination of a vessel having a groove around the mouth thereof, a cover for said vessel having a rib on the under side for engaging the said groove, a disk or washer pressed between said rib and groove, oppositely-disposed notches in the said cover and an extensible clip engaging in said notches for fixing said cover in position, substantially as described.

2. The combination of a vessel, a notched cover, a rib on said cover, a groove in the mouth of said vessel, in which the rib engages, a clip adapted to engage in the notches of said cover, hooked ends on said clip to engage the vessel and hold the stopper thereon, and a finger-piece on said clip for enabling the vessel to be lifted, substantially as described.

3. The combination of a vessel having a groove around the mouth thereof, a cover with a rib'to fit into said groove, an extensible clip arranged across said cover, andhooked ends on said clip to engage the vessel and hold the cover in position, substantially as described. 4E. \The combination of a vessel having a groove around its mouth, a cover with a rib to fit into said groove, and diametrically-arranged notches in its edge, a central plug or projection on said cover adapted to fit into the mouth of said vessel, and an extensible clip having hooked ends to engage with said notches and the vessel to hold the said cover in position, substantially as described.

In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 3d day of December, 1902.
